摘要：
The title compound, C12H6F6N2O3, belongs to a class of mesoionic compounds. The crystal packing exhibits a short intermolecular N(heterobicycle)center dot center dot center dot O(N-trifluoroacetyl) contact of 2.8689 (11) angstrom, which indicates that the principal location of the negative charge is near the chain C and O atoms of the N-trifluoroacetyl group. The F atoms of one trifluoromethyl group are disordered over two positions, the site occupancy ratio being ca 3:2.
